The Mass Effect Facebook Page has word that, contrary to previous indications, BioWare is actively looking at the negative backlash to the conclusion of Mass Effect 3 and the resolution of the Commander Shepard trilogy in the action/RPG series (which has apparently inspired FTC complaints). Here's word:

We are aware that there are concerns about a recent post from this account regarding the ending of the game. In this post it was stated that at this time we do not have plans to change the ending.

We would like to clarify that we are actively and seriously taking all player feedback into consideration and have ruled nothing out. At this time we are still collecting and considering your feedback and have not made a decision regarding requests to change the ending.

Your feedback and opinions are of the utmost importance to us. We apologize for any confusion this has caused. Our top priority regarding this discussion is to keep communication with you, our loyal fans, open and productive.

Isn't it sort of the case of "You can only have one first impression"? Meaning you already have your ending, how can you really change it now and have it seem right? Patrick Duffy makes an appearance and dreamnt it all?

The ending should have been, they stopped the synthetics killing the organics in whole. Then have a Jacob's Ladder type of ending where you zoom out to a larger picture and Shepard (ordinary joe) is on a operating table, the DR. says; "we tried everything but we couldn't stop the cancer from spreading". Meaning the organics were really a disease, but a disease never looks at itself at one, the synthetics were the cure. Or maybe not.

But any and all endings now are way too late to consider now. The game has shipped with it's ending.
